Bad Company 2 sales total 9m, Battlefield 3 pre-orders now 10 times BC2

When we checked in on the Battlefield series back in May, Bad Company 2 had sold seven million units, and pre-orders for the upcoming Battlefield 3 had hit seven times the number seen for Bad Company 2.

Now those figures have increased yet again: BC2 has hit nine million units ("demonstrating strong cross-platform results"), while BF3 pre-orders have touched ten times the BC2 figure.

At least part of the BC2 surge can be explained by a recent feature in the Steam summer sales, while BF3 is no doubt explained by its huge presence at E3, which we covered extensively.
